I put SLP's cold-air induction on my '97 Formula a couple years ago. Last November a young lady darted-out in front of me to get T-boned and buy me a new SLP "RAM-AIR" hood. Based on the 20HP gain SLP quoted for the cold-air setup vs the 15hp gain they quoted for the ram-air package, I just left the cold-air in place and have enjoyed the looks of the non-functioning ram-air hood.
With the Augusta, GA heat in the high 90's, my quarter mile times have diminished by 4/10ths. I started thinking about the intake air temperature and what I could do to cool it down. That's when I put my hand on the steel "cold-air" pipes after a short drive. They were HOT.
I decided drag-radials were a better $300 investment than the hardware to make the ram-air hood functional (I get little traction off the line); so I dreamed-up a $10 modification, I wondered what you guys think of it...
Basically I just went to home-depot and bought some silver-coated insulation and matching silver (reflective) tape. I cut and taped the insulation around the cold-air induction pipe from where it enters the inside of the hood up to the MAF. The idea being that the "cold-air" passing through the steel (highly conductive) pipe is probably gaining a few degrees during the trip.
I may not be able to test this mod at the track before I get my new drag-radials on the car, so I might not know how beneficial it actually is. My question is, do you think it is a good enough idea to test independently? Do you think it will have any impact on my quarter mile time?
Thanks!
